How EMI is Calculated — The Formula
Banks use a reducing balance method to calculate EMI. This means interest is calculated each month on the remaining outstanding loan balance — not the original loan amount. As you pay EMI every month, your outstanding balance reduces, and so does the interest component of each subsequent EMI.
EMI Formula:
EMI = P × r × (1+r)^n / [(1+r)^n – 1]
Where:
- P = Principal loan amount (e.g., ₹30,00,000)
- r = Monthly interest rate = Annual Rate ÷ 12 ÷ 100 (e.g., 8.5% ÷ 12 ÷ 100 = 0.00708)
- n = Total number of monthly installments (e.g., 20 years × 12 = 240)
Real Example: ₹30 Lakh Home Loan at 8.5% for 20 Years
| Detail | Amount |
|---|---|
| Loan Amount | ₹30,00,000 |
| Interest Rate | 8.5% p.a. |
| Tenure | 20 years (240 months) |
| Monthly EMI | ₹26,036 |
| Total Amount Paid | ₹62,48,640 |
| Total Interest Paid | ₹32,48,640 |
| Interest as % of Principal | 108% — you pay more interest than principal! |
EMI Amortization — First 6 Months
| Month | EMI | Principal | Interest | Balance |
|---|---|---|---|---|
| 1 | ₹26,036 | ₹3,786 | ₹22,250 | ₹29,96,214 |
| 2 | ₹26,036 | ₹3,814 | ₹22,222 | ₹29,92,400 |
| 3 | ₹26,036 | ₹3,842 | ₹22,194 | ₹29,88,558 |
| 6 | ₹26,036 | ₹3,957 | ₹22,079 | ₹29,74,044 |
| 12 | ₹26,036 | ₹4,197 | ₹21,839 | ₹29,47,435 |
| 60 | ₹26,036 | ₹6,497 | ₹19,539 | ₹27,61,898 |
Notice that in the first month, ₹22,250 (85%) of your EMI goes to interest and only ₹3,786 (15%) reduces the principal. This is why prepayment in the early years is so powerful.
How RBI Rate Changes Affect Your EMI
Almost all home loans in India are now linked to an external benchmark rate — either the RBI Repo Rate or the bank's own MCLR (Marginal Cost of Lending Rate). Since October 2019, all new home loans from banks must be linked to an external benchmark.
When RBI increases repo rate by 0.25%:
Your home loan interest rate increases by 0.25% within 3 months. For a ₹30L loan at 20 years, this adds ₹498/month to your EMI — and ₹1.2 lakh in total extra interest over the remaining tenure.
When RBI cuts repo rate:
Your bank must pass on the rate cut within 3 months. This reduces your EMI — or keeps EMI same but shortens tenure. Most banks reduce tenure by default. Ask your bank explicitly if you want the EMI reduced instead.
5 Proven Ways to Reduce Total Home Loan Interest
1. Part Prepayment — The Most Powerful Tool
Even a single prepayment of ₹1 lakh in year 3 of a ₹30L, 20-year loan at 8.5% saves approximately ₹2.9 lakh in interest and cuts 14 months off the tenure. Prepayment is most effective in the early years when the outstanding principal is highest. Most banks allow unlimited prepayment on floating rate loans with zero penalty.
2. Reduce Tenure, Not EMI
If your income increases, ask your bank to reduce tenure instead of reducing EMI. A 20-year loan reduced to 15 years saves massive interest. Use our EMI Calculator to compare 15-year vs 20-year payments.
3. Balance Transfer to a Lower Rate Bank
If your current rate is 9% and another bank offers 8.25%, transferring saves significant money. Balance transfer makes most sense when at least 10–15 years of loan tenure remains. Factor in processing fee (0.5%–1%) before deciding.
4. Make EMI Payments on Time
Late EMI payments attract penalty (typically 2% p.a. on overdue amount) and damage your CIBIL score, making future borrowing expensive. Set up auto-debit to never miss an EMI.
5. Choose Floating Rate Over Fixed
Fixed rate home loans are typically 1–2% higher than floating rates. Over a 20-year period, this difference costs lakhs. Unless you are taking a loan at a market bottom, floating rate is almost always cheaper long-term.
